The following constitutes Amendment # 2 to the Schedule 13D filed by the
undersigned (the "Schedule 13D").

Item 3.           Source and Amount of Funds or Other Consideration.
                  -------------------------------------------------

The aggregate purchase price of the 303,013 Shares of Common Stock owned
beneficially by JANA Partners LLC is $ 2,226,742. Such Shares of Common Stock
were acquired with investment funds in accounts under management.

Item 4.           Purpose of Transaction.
                  ----------------------

                  JANA Partners LLC commends Middleby's CEO Selim Bassoul and
his management team on their very successful integration of the Blodgett
acquisition and the resulting gains in the share price. We have determined to
realize a portion of such gains at present, but remain supportive of the
company.

                  Depending upon overall market conditions, other investment
opportunities available to the Reporting Person, and the price and availability
of Shares of Common Stock, the Reporting Person may endeavor to increase or
decrease their position in the Issuer through, among other things, the purchase
or sale of Shares of Common Stock on the open market or in private transactions
or otherwise, on such terms and at such times as the Reporting Persons may deem
advisable. Neither the Reporting Person nor the Principals has any present plan
or proposal which would relate to or result in any of the matters set forth in
subparagraphs (a) - (j) of Item 4 of Schedule 13D.

Item 5.           Interest in Securities of the Issuer.
                  ------------------------------------

(a) The aggregate percentage of Shares of Common Stock reported owned
beneficially by the Reporting Person is based upon 9,033,722 Shares outstanding,
which is the total number of Shares of Common Stock outstanding as reported in
the Issuer's Quarterly Report on Form 10-Q for the quarter ended June 30, 2003.

As of the close of business on September 9, 2003, JANA Partners LLC beneficially
owned 303,013 Shares of Common Stock, constituting approximately 3.4 % of the
Shares outstanding.

(b) The Reporting Person has sole voting and dispositive powers with respect to
the Shares reported herein, which powers are exercised by the Principals. All of
such Shares were acquired in open-market transactions.

(c) Schedule A annexed hereto lists all transactions in the Issuer's Common
Stock in the last sixty days by the Reporting Person.

(d) No person other than the Reporting Person is known to have the right to
receive, or the power to direct the receipt of dividends from, or proceeds from
the sale of, such Shares of the Common Stock.

(e) JANA PARTNERS LLC has ceased to be the beneficial owner of more than five
percent of the outstanding common stock of Middleby Corporation.
